DETAILED DESCRIPTION OF THE INVENTION

The exemplary embodiments are described more fully hereinafter withreference to the accompanying drawings. The invention may, however, beembodied in many different forms and should not be construed as limitedto the exemplary embodiments set forth herein. In the drawings, thesizes and relative sizes of layers and regions may be exaggerated forclarity.

It will be understood that when an element or layer is referred to asbeing “on,” “connected to” or “coupled to” another element or layer, itcan be directly on, connected or coupled to the other element or layeror intervening elements or layers may be present. In contrast, when anelement is referred to as being “directly on,” “directly connected to”or “directly coupled to” another element or layer, there are nointervening elements or layers present. Like or similar referencenumerals refer to like or similar elements throughout. As used herein,the term “and/or” includes any and all combinations of one or more ofthe associated listed items.

It will be understood that, although the terms first, second, third etc.may be used herein to describe various elements, components, regions,layers, patterns and/or sections, these elements, components, regions,layers, patterns and/or sections should not be limited by these terms.These terms are only used to distinguish one element, component, region,layer pattern or section from another region, layer, pattern or section.Thus, a first element, component, region, layer or section discussedbelow could be termed a second element, component, region, layer orsection without departing from the teachings of an exemplary embodiment.

Spatially relative terms, such as “beneath,” “below,” “lower,” “above,”“upper” and the like, may be used herein for ease of description todescribe one element or feature's relationship to another element(s) orfeature(s) as illustrated in the figures. It will be understood that thespatially relative terms are intended to encompass differentorientations of the device in use or operation in addition to theorientation depicted in the figures. For example, if the device in thefigures is turned over, elements described as “below” or “beneath” otherelements or features would then be oriented “above” the other elementsor features. Thus, the exemplary term “below” can encompass both anorientation of above and below. The device may be otherwise oriented(rotated 90 degrees or at other orientations) and the spatially relativedescriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particularan exemplary embodiment only and is not intended to be limiting of theinvention. As used herein, the singular forms “a,” “an” and “the” areintended to include the plural forms as well, unless the context clearlyindicates otherwise.

As such, variations from the shapes of theillustrations as a result, for example, of manufacturing techniquesand/or tolerances, are to be expected. Thus, an exemplary embodimentshould not be construed as limited to the particular shapes of regionsillustrated herein but are to include deviations in shapes that result,for example, from manufacturing. The regions illustrated in the figuresare schematic in nature and their shapes are not intended to illustratethe actual shape of a region of a device and are not intended to limitthe scope of the invention.

Unless otherwise defined, all terms (including technical and scientificterms) used herein have the same meaning as commonly understood by oneof ordinary skill in the art to which this invention belongs. It will befurther understood that terms, such as those defined in commonly useddictionaries, should be interpreted as having a meaning that isconsistent with their meaning in the context of the relevant art andwill not be interpreted in an idealized or overly formal sense unlessexpressly so defined herein.

Turning now to FIGS. 1 and 2, FIG. 1 is a cross sectional viewillustrating a window structure of a comparative example, and FIG. 2 isa plan view of the window structure of FIG. 1. FIG. 1 a cross-sectionalview of the window structure of FIG. 2 cut along the line I-I′. In FIG.1, a camera sensor that may be disposed facing the window structure isalso shown.

Referring now to FIGS. 1 and 2, a window structure 50 may include awindow 10 and a design layer structure 20 and a light shield layer 30sequentially stacked on the window 10. The design layer structure 20 mayinclude a first design layer 22 and a second design layer 24sequentially stacked on the window 10, which is a transparent material,e.g., glass, plastic, etc. The first and second design layers 22 and 24may have a chromatic color or a white color. The design layer structure20 may have a first hole 25 exposing a top surface of the window 10.Accordingly, as the design layer structure 20 includes the first andsecond design layers 22 and 24, the first hole 25 may have a step shapeof which a diameter may increase from a bottom portion adjacent to thetop surface of the window 10 to a top portion distant from the topsurface of the window 10. The first hole 25 may have a circular shapewhen view from a top side.

The light shield layer 30 may have a black color or a gray color. Thelight shield layer 30 may have a second hole 35 in fluid communicationwith the first hole 25, and the second hole 35 may have a diameterlarger than that of the first hole 25. The second hole 35 may have acircular shape when viewed from a top side. The first and second holes25 and 35 may be concentric circles.

A camera sensor 90 may be disposed facing the first and second holes 25and 35, and the camera sensor 90 may be disposed on a substrate 80. Alight that is reflected from an object (not shown) and passes throughthe window 10 and the first hole 25 of the design layer structure 20 maybe incident on the camera sensor 90, and a portion of the light may bereflected from the camera sensor 90 and be incident on the light shieldlayer 30 and the design layer structure 20. A portion of the lightincident on the design layer structure 20 may be reflected again (seerays A1 of FIG. 1) and be incident on the camera sensor 90. Thus, thecamera sensor 90 may detect a color of the design layer structure 20regardless of a color of the object.

If the design layer structure 20 has a very thin thickness, the portionof the light that is reflected from the object, passes through thewindow 10 and is incident on the design layer structure 20 may passthrough the design layer structure 20 (see rays A2 of FIG. 1), and inthis case the camera sensor 90 may also detect the color of the designlayer structure 20. However, a light that is incident on a portion ofthe design layer structure 20 covered by the light shield layer 30 maynot pass through the light shield layer 30, and thus may not be incidenton the camera sensor 90.

As a result, a light having passed through the window 10 may bereflected diffusely at the design layer structure 20 not covered by thelight shield layer 30, and the color of the design layer structure 20that is not related to the color of the object may be detected by thecamera sensor 90. Accordingly, the color of the design layer structure20 may be transferred to surroundings of the image of the object, i.e.,a kind of vignette may occur.

Turning now to FIGS. 3 and 4, FIG. 3 is a cross sectional viewillustrating a window structure in accordance with an exemplaryembodiment, and FIG. 4 is a plan view of the window structure of FIG. 3.FIG. 3 is a cross-sectional view of the window structure of FIG. 4 cutalong the line II-II′ of FIG. 4. In FIG. 3, a camera sensor that may bedisposed facing the window structure is also shown.

Referring now to FIGS. 3 and 4, a window structure 100 may include awindow 110, a first design layer structure 120 and a first light shieldlayer 130 sequentially stacked on the window 110, and a first lightabsorption layer 140. The window 110 may be a flat plate, and have afirst surface 112 and a second surface 114 opposing the first surface112. The window 110 may include a light transmission material, e.g., asynthetic resin such as acryl, or glass.

The first design layer structure 120 may be formed on the first surface112 of the window 110. In an exemplary embodiment, the first designlayer structure 120 may include a first design layer 122 and a seconddesign layer 124 sequentially stacked on the window 110. The first andsecond design layers 122 and 124 may have a chromatic color or a whitecolor. In an exemplary embodiment, the first and second design layers122 and 124 may have substantially the same color.

The first design layer structure 120 may have a first hole 125 exposinga portion of the first surface 112 of the window 110. In an exemplaryembodiment, the first hole 125 may have a circular shape when viewedfrom a top side. Accordingly, as the first design layer structure 120includes the first and second design layers 122 and 124, the first hole125 may have a step shape of which a diameter may increase from a bottomportion adjacent to the first surface 112 of the window 110 to a topportion distant from the first surface 112 of the window 110. That is,the second design layer 124 may not cover the whole first design layer122, and thus the first design layer 122 may be partially exposed.

FIGS. 3 and 4 show the first design layer structure 120 having the twodesign layers 122 and 124 sequentially stacked, however, the firstdesign layer structure 120 may have more than two design layers, and thefirst hole that may be defined as a sidewall and/or a top surface of thedesign layers may also have a step shape of which a diameter mayincrease from a bottom portion adjacent to the first surface 112 of thewindow 110 to a top portion distant from the first surface 112 of thewindow 110. Alternatively, the first design layer structure 120 may haveonly one design layer. Hereinafter, for the convenience of explanation,only the case in which the first design structure 120 has two designlayers will be illustrated.

The first light shield layer 130 may have a black color or a gray colorand be formed on the second design layer 124 of the first design layerstructure 120, and have a second hole 135 in fluid communication withthe first hole 125. In an exemplary embodiment, the second hole 135 mayhave a diameter larger than that of the first hole 125. The second hole135 may have a circular shape when viewed from a top side. The first andsecond holes 125 and 135 may be concentric circles. The first lightshield layer 130 may not cover the whole second design layer 124, andthus the second design layer 124 may be partially exposed. Thus, a holestructure including the first and second holes 125 and 135 may have astep shape of which a diameter may increase from a bottom portionadjacent to the first surface 112 of the window 110 to a top portiondistant from the first surface 112 of the window 110.

The first light absorption layer 140 may cover at least a portion of thefirst design layer structure 120 exposed by the first hole structure,i.e., the first and second holes 125 and 135, and may have a third hole145 exposing a portion of the first surface 112 of the window 110. Thatis, the first light absorption layer 140 may cover a sidewall of thefirst design layer 122, a portion of a top surface of the first designlayer 122 and a sidewall of the second design layer 124, which may beexposed by the first hole 125 or may define the first hole 125, and aportion of a top surface of the second design layer 124 exposed by thesecond hole 135. The third hole 145 may be formed within the first holestructure consisting of the first and second holes 125 and 135 and mayhave a diameter that is smaller than that of the first hole structure.In an exemplary embodiment, the third hole 145 and the first hole 125and/or the second hole 135 may be concentric circles when viewed from atop side. In an exemplary embodiment, the third hole 145 may have asidewall substantially perpendicular to the first surface 112 of thewindow 110. That is, the first light absorption layer 140 may have asidewall substantially perpendicular to the first surface 112 of thewindow 110.

In an exemplary embodiment, the first light absorption layer 140 maycover not only a portion of the first design layer structure 120, butalso a sidewall of the first light shield layer 130, which may beexposed by the second hole 135 or may define the second hole 135, and aportion of a top surface of the first light shield layer 130 adjacent tothe second hole 135. A boundary of the first light absorption layer 140may be a circle, and the first and second holes 125 and 135 and theboundary of the first light absorption layer 140 may be concentriccircles. In an exemplary embodiment, the first light absorption layer140 may have a top surface substantially parallel to the first surface112 of the window 110. The first light absorption layer 140 may have ablack color or a gray color. In an example embodiment, the first lightshield layer 130 may have a gray color and the first light absorptionlayer 140 may have a black color.

In FIG. 4, the first design layer structure 120 and the first lightshield layer 130 cover entirely the first surface 112 of the window 110except for the first to third holes 125, 135 and 145, however, the firstdesign layer structure 120 and the first light shield layer 130 may beformed only at a portion of the first surface 112 of the window 110adjacent to the first light absorption layer 140 according to a desireddesign.

A camera sensor 190 may be disposed facing the third hole 145, and thecamera sensor 190 may be disposed on a substrate 180. Accordingly, thethird hole 145 may serve as a path through which a light reflected froman object (not shown) may pass.

A light that is reflected from the object and passes through the window110 and the third hole 145 may be incident on the camera sensor 190, anda portion of the light may be reflected from the camera sensor 190 andtoward the first design layer structure 120, the shield layer 130 or thefirst light absorption layer 140. However, the first light absorptionlayer 140 may cover portions of the first design layer structure 120exposed by the first and second holes 125 and 135, and thus lightreflected off the camera sensor 190 may be blocked from being incidenton the first design layer structure 120 by the first light absorptionlayer 140 and the first light shield layer 130. Thus, the color of thefirst design layer structure 120, which may be chromatic or white, maynot be detected by the camera sensor 190.

Even though the first design layer structure 120 may have a very thinthickness, a light that is reflected from the object, passes through thewindow 110 and the first design layer structure 120, and is incident onthe first hole 125 or the second hole 135 may be absorbed by the firstlight absorption layer 140, so that the light may not be incident on thecamera sensor 190. A light that passes through the window 110 and isincident on a portion of the first design layer structure 120 covered bythe first light shield layer 130 may also be blocked by the first lightshield layer 130, so that the light that interacts with first designlayer structure 120 does not reach camera sensor 190.

Accordingly, the color of the first design layer structure 120 that isnot related to the color of the object may be prevented from beingincident on the camera sensor 190, and the vignetting, i.e., the colorof the first design layer structure 120 that would otherwise betransferred to surroundings of the image of the object, may beprevented.

Turning now to FIG. 5, FIG. 5 is a plan view illustrating a windowstructure in accordance with an exemplary embodiment. The windowstructure may be substantially the same as that of FIGS. 3 and 4, exceptfor the boundary of the light absorption layer 140. Thus, like referencenumerals refer to like elements, and detailed descriptions thereon areomitted herein.

A window structure 100 may include a window 110, a first design layerstructure 120 and a first light shield layer 130 sequentially stacked onthe window 110, and a second light absorption layer 142. In an exemplaryembodiment, the second light absorption layer 142 may have a rectangularshaped boundary.

The window structure 100 may have other types of boundary, e.g., anellipse, polygon, etc., except for the circle or the rectangle of thefirst and second light absorption layers 140 and 142, respectively.Hereinafter only the window structure having the boundary of circle willbe illustrated for the convenience of explanation.

Turning now to FIGS. 6-13, FIGS. 6, 8, 10 and 12 are cross-sectionalviews illustrating a method of manufacturing a window structure inaccordance with an exemplary embodiment, and FIGS. 7, 9, 11 and 13 areplan views of the window structure thereof. More specifically, FIGS. 6,8, 10 and 12 are cross-sectional views of the window structure of FIGS.7, 9, 11 and 13, respectively, cut along the line III-III′ of FIGS. 7,9, 11 and 13. FIGS. 6 to 13 show a method of manufacturing the windowstructure of FIGS. 3 and 4, however, these may not be limited thereto.

Referring now to FIGS. 6 and 7, the window 110 may include a lighttransmission material, e.g., a synthetic resin such as acryl, or glass.The window 110 may include a first surface 112 and a second surface 114opposing the first surface 112.

The first design layer 122 may be formed on the first surface 112 of thewindow 110. In an exemplary embodiment, the first design layer 122 maybe formed by a screen printing process using a mesh. That is, a mesh(not shown) for forming a desired pattern may be mounted on the firstsurface 112 of the window 110, ink may be sprayed or dropped onto themesh, and a rubber plate may press the sprayed or dropped ink to formthe first design layer 122 having a desired pattern. In an exemplaryembodiment, the first design layer 122 may be formed using ink of achromatic color or a white color, and a metal powder, e.g., silverpowder may be included in the ink.

In an exemplary embodiment, the first design layer 122 may be formed toinclude a first hole 125 therethrough. The first hole 125 may have acircular shape when viewed from a top side. A drying process may befurther performed after the first design layer 122 is printed on thefirst surface 112 of the window 110.

Referring now to FIGS. 8 and 9, a second design layer 124 may be formedon the first design layer 122. The second design layer 124 may be formedby a screen printing process using a mesh as with the first design layer122. In an exemplary embodiment, the second design layer 124 may beformed using chromatic or white ink, and may be formed using ink havingsubstantially the same color as that of the first design layer 122.

In an exemplary embodiment, the second design layer 124 may be formed tohave a hole therethrough. The hole in second design layer 124 and thefirst hole 125 may be concentric circles. Thus, the hole in seconddesign layer 124 may be in fluid communication with the first hole 125.

In an exemplary embodiment, the hole in second design layer 124 may beformed to have a diameter larger than that of the first hole 125 inorder for the second design layer 124 may not be formed on a portion ofthe first surface 112 of the window 110 exposed by the first hole 125during the screen printing process. Thus, the first design layer 122 maynot be completely covered by the second design layer 124, and a portionof the first design layer 122 adjacent to the first hole 125 may beexposed.

Hereinafter, the first hole 125 through the first design layer 122together with the hole through the second design layer 124 in fluidcommunication therewith may be referred to as the first hole 125.
